Metal oxide coupling with carbon materials holds great promise for lithium storage. Herein, multilevel coupled cobalt oxide–graphene (CoO/CO3O4–G) hybrids were fabricated by in situ assembly of Co hydroxide precursors and a calcination process. The oxygen‐containing functional groups on the graphene surface act as bridging sites and tend to bond with Co2+ ions, effectively modifying the morphology...
A safe, high‐capacity, and long‐life Li metal anode is highly desired due to recent developments in high‐energy‐density Li–metal batteries. However, there are still rigorous challenges associated with the undesirable formation of Li dendrites, lack of suitable host materials, and unstable chemical interfaces. Herein, a carbon nanofiber‐stabilized graphene aerogel film (G‐CNF film), inspired by constructional...
